I'm currently using the .NET Framework wrapper for opening an external
process with redirected stdin/stdout/stderr. AFAIK only a few essential
stream methods are implemented, and some of those only partially; so
checking FIFO size, space, and return values isn't possible. Given your
statements, I now wonder if this wrapper is responsible for both the
dropped commands and out-of-order events. It wouldn't be the first time
.NET has caused me headaches. I'll look into accessing these streams at a

In response to:
set_property tv_brightness 50
The Windows binary release prints:
Failed to set property 'tv_brightness' to '50'.
And r37205 prints:
Unknown property: 'tv_brightness'
I logged these from my program, which doesn't distinguish between
stdout/stderr, so I'm not sure which stream these lines came in on. Or
whether these are in the correct order, if the .NET wrapper is broken.

Unfortunately, I'm using the OSD.

I like this. ;)
